whens the last time you drove in nj? i can tell you that 99.999% of the small block cars around her that are stock height (some higher) that are running the "cheap" headers all have smashed tubes. just a fact of life around here. power wise im sure they are close. hell the cheap ones may turn out yo make more power for all i know but id much rather spend the money for a tti or dougs and not have to cringe everytime i come to a dip in the road. the plug access is an added bonus.
